Check out a sample textbook solution- a. Write a FractionDemo program that instantiates several Fraction objects and demonstrates that their methods work correctly. Create a Fraction class with fields that hold a whole number, a numerator, and a denominator. In addition: Create properties for each field. The set access or for the denominator should not allow a 0 value; the value defaults to 1. Add three constructors. One takes three parameters for a whole number, numerator, and denominator. Another accepts two parameters for the numerator and denominator; when this constructor is used, the whole number value is 0. The last constructor is parameterless; it sets the whole number and numerator to 0 and the denominator to 1. (After construction, Fractions do not have to be reduced to proper form. For example, even though 3/9 could be reduced to 1/3, your constructors do not have to perform this task.) Add a Reduce() method that reduces a Fraction if it is in improper form. For example, 2/4 should be reduced to 1/2. Add an operator+() method that adds two Fractions. To add two fractions, first eliminate any whole number part of the value. For example, 2 1/4 becomes 9/4 and 1 3/5 becomes 8/5. Find a common denominator and convert the fractions to it. For example, when adding 9/4 and 8/5, you can convert them to 45/20 and 32/20. Then you can add the numerators, giving 77/20. Finally, call the Reduce() method to reduce the result, restoring any whole number value so the fractional part of the number is less than 1. For example, 77/20 becomes 3 17/20. Include a function that returns a string that contains a Fraction in the usual display format—the whole number, a space, the numerator, a slash (D, and a denominator. When the whole number is 0, just the Fraction part of the value should be displayed (for example, 1/2 instead of 0 1/2). If the numerator is 0, just the whole number should be displayed (for example, 2 instead of 2 0/3). b. Add an operator*() method to the Fraction class created in Exercise 11a so that it correctly multiplies two Fractions. The result should be in proper, reduced format. Demonstrate that the method works correctly in a program named FractionDemo2. c. Write a program named FractionDem03 that includes an array of four Fractions. Prompt the user for values for each. Display every possible combination of addition results and every possible combination of multiplication results for each Fraction pair (that is, each type will have 16 results).arrow_forwardCreate a class named Person that holds the following fields: two String objects for the person’s first and last name and a LocalDate object for the person’s birthdate.

The class contains: ■ Two double data fields named width and height that specify the width and height of the rectangle. The default values are 1 for both width and height. ■ A no-arg constructor that creates a default rectangle. ■ A constructor that creates a rectangle with the specified width and height. ■ A method named getArea() that returns the area of this rectangle. ■ A method named getPerimeter() that returns the perimeter.Draw the UML diagram for the class and then implement the class.

In this exercise, we are going to create a phonebook that automatically sorts everytime a new number is added to the phonebook. A PhoneNumber class has been created already that has the instance variables name and number. Your job is to create the PhoneBook class that will store an ArrayList of PhoneNumbers. The PhoneBook class does not have a constructor - it only contains an ArrayList that can store the individual phone numbers that are added to it. There should be three methods in the PhoneBook class: addNumber- This method takes a PhoneNumber and adds it to the directory. Once the number has been added, the sort method is called on the directory to sort that new address into the phone book. sort- This method sorts the directory in alphabetical order A-Z.a.
